It's definitely more than 76 liters. If I remember correctly, it is 80 l. My spots have the same type of chop, it is an excellent choice for these conditions, and s.o. your weight should plane in 15 kn. with a 6.3. IMHO it is one of the best boards Starboard have ever made (I own two of these, for 2 very choppy spots in 2 different countries). I do not like to rig bigger than 6.3 on this board. Go for it, you won't regret it, but try it first, because I know many people who didn't like it, and sold it after sailing it a few times. Apparently, in 2009 there was an issue with a Cobra mould that was not according to Starboard's specs, so test it before you buy it.

Hi rww, excuse me, i'm not from the Team but own an Isonic 94 2007 and weight 67k (almost as you) and am 1.85 , didn't test the 76 (that is84L and only 4cm wider) but am using a lot my 94L (really 93), i sail almost the same water as you, a large lake that get large chop between 15/22 kt. For that i carry Ka salis between 5.8 to 6.6 and Venom fines between 30 to 36cm, that gear rides fantastic, specially because the 94 is not too wide and Venoms forgive everything. Also rode the 94 with 5.3 , not ideal but goes fine, take a look at 2007 http://2007.star-board.com/viewpage.php?page_id=31

I have actually ended up buying the 2007 Isonic 94, and so far am very pleased that I did. Have only had a chance to use it a few times and am still getting the feel of things after not having sailed for many years. As far as sails go, I have a 6.2 NP RS Slalom Mk iv and a 5.5 NP RS Slalom Mk iii that I picked up for very good prices. Am pleased with both of those too so far. With my weight, I managed to get planing with the 6.2 in only 10 - 12 knots using a Select 31cm fin, which is all I have at this stage.

Thanks all for your advice. I am more than happy with my choice of the 2007 Isonic 94, but still have the opportunity to buy a brand new old stock 2009 Isonic 76 at a very good price. I am tempted to buy it as my high wind board. Would it be noticeably better in high wind than the 94 with my light weight (62kg)??

sounds like you just got the 94
now you are so excited you are ready for more ??
you sound like me - i call it "stop the shop"
take a breather and evaluate what you got, where you sail, your skills , etc
how often will you use it , could you water start it , storage , etc
in the business they call this the king question
ROI = king in french
and stands for return on investment
i have a board i used maybe 5 times in 10 years
now it is so old, no-one will buy it
wasted my money ...
